Title:
  Flow drop on agent restart with ovs firewall driver

Status in neutron:
  Fix Released

Bug description:
  Hello,

  Opening a bug as per Slawek Kaplonski suggestion on the mailing list
  (http://lists.openstack.org/pipermail/openstack-
  discuss/2020-September/017108.html)

  We are experiencing flow drops when restarting the ovs agent.


  Symptom example when restarting the agent:
  http://paste.openstack.org/show/797669/

  * We are running neutron 14.0.2
  * Neutron configuration: http://paste.openstack.org/show/797646/
  * ml2 configuration: http://paste.openstack.org/show/797647/
  * openvswitch_agent configuration: all defaults, nothing customized (conf file only contains empty « [DEFAULT] »)
  * ovs agent debug logs: file attached (wasn't able to paste all of it on paste.openstack.org)

  Several tests been conducted for different types of flow, east-west,
  north-south, flat provider-networks, self-service networks, with or
  without our corporate proxy. In each configuration some flow would
  cut.

  If I switch back to firewall_driver=iptables_hybrid in the
  securitygroup section of ml2 configuration, we do not experience the
  issue anymore.


  Let me know if additional information should be provided.

  As soon as I got some time to deploy a devstack I’ll have a look if
  the issue can be reproduced using lastest master branch.
